On September 26, the European Day of Languages is celebrated worldwide to emphasize linguistic diversity and intercultural understanding. The significance of this day was conveyed to our students through an event organized by the Foreign Languages Department at our school. Preparatory class students participated in the activity titled “Which language…?” including German, French, and Spanish expressions supported by technological applications. In this way, they had the opportunity to closely explore the richness that different languages bring to the world. Thanks to the event, students gained awareness of the role of language learning in building bridges between individuals and societies, and they completed the day in a productive and enthusiastic way.
